LATCH DEVICE OF DOOR

Document Type and Number:

WIPO Patent Application WO/2007/055200

Kind Code:

A1

Abstract:

A simply structured and smoothly operable latch device of a door in which a latch can be infallibly released by operating a handle from any of upper, lower, right, and left sides. The handle (1) having operation parts (1e) at the upper, lower, left, and right inner edges of the front opening part thereof is received in a handle receiving part (14) formed in a door (3) and having an opening in its front surface. The handle (1) can be moved to a non-operating position where the rear surface of the handle abuts on the rear end surface of the handle receiving part (14) or to an operating position where the handle (1) is tilted so that one of the upper and lower edges or one of the left and right edges is nearer to the person operating the handle (1) than the other. The handle (1) is biased toward the non-operating position by a spring (17), and the handle (1) and the latch are linked with each other by a linkage means (34) so that the latch can be moved to the non-engaging position when the handle (1) is moved to the operating position.
